Facebook Messenger gets a new Like sticker pack, adds dislike button for the first time.

Facebook has updated its messenger app with new line of stickers that also includes a dislike button. The dislike option is available for mobile and desktop versions of Facebook messenger for now. Users can access the new sticker pack from the sticker shop inside the messenger app.

Facebook's dislike button has been much requested by users, while the social media site won’t bring it to comments and status updates. The button for now is available for messenger users.

Facebook introduced Stickers in April this year, but a recent hackathon has resulted in a “Likes” sticker pack that includes a sore thumb, fiery thumb, poke, and lots more. In all Facebook has introduced 12 icons in total including Facebook hand handing out flowers, holding a glass of champagne or showing the victory sign.

The Like button is “the quickest way for people to share content with their friends,” as Facebook states on its developers page. It can also work for Facebook to learn what users like and serve relevant ads based on it.

According to recent reports, Facebook will start selling video ads from this week. The ads will automatically play in the users news feed on the web and mobile devices. Facebook will run 15 second ads no more than three times a day for a user. According to sources the social networking site will be displaying HD ads with easy to use playback features starting this Thursday. The video ads will likely capture a share of approx $ 66.4 million that was expected to go to US television this year.
